I To all whom it may concern Be it known that l, GEORGE C. JENSEN, acitizen of the United States, residing at Oakland, in the county ofAlameda and State of (lalifornia, have invented certain new and usefulimprovements in Bolt-GP- erated Locking Devices, of which the followingis a specification.

In the construction of locking devices for motor vehicles it isnecessary that the same be of a type capable of construction and installation at an extremely low cost; consist of but few parts and it isdesirable that the locking mechanism. have but one removable part, thatbeing the key which is adapted for releasing the bolt locking latch ormember.

It is further desirable that a construction be provided consisting ofbut few parts which in addition to providing a lock for the shift rodsor devices is adapted to also provide an interlock for the same wherebyone of said rods is locked from operative movement during such time asthe other rod is moved from. neutral to operative position.

lViti: the above mentioned and other obiects in view, the inventionconsists in the novel construction and coinhination of parts hereinafterdescribed ihustrated in the accompanyingdrawings, and seti'orth in theclaims hereto appended, it being understood that various changes in theform, proportion, size and minor details of construction withinthe-scope or the claims may be resorted to without departing fromthespirit or sacrificing any of the advantages of the invention.

' To more fully comprehend the invention reference is directed to theaccompanying drawings, wherein,

Figure 1 is a vertical sectional view of the preferred embodiment oi? myinvention illustratingthe parts in position to lockthe shifter rods fronoperative movement.

Fig. 2 is a sectional view taken on line 2-.2 of Fig. 1 and viewed inthe direction of the arrows. I

Refcrringmore particularly to the. several views of the drawings whereinlike characters 'of reference designate corresponding parts, 1 indicatesa suitable member, preferably the end wallor cover of a transmissioncase'housing, although the same may be entirely independent. of thetransmission case or housing if desired. The member 1 is 'ovide at 'sseeddntervais with the a "93 H3.

tioned within the bore 5 intermediate the.

shift rods or devices 3 is an'elongated interlocking member 6 preferablyoval in plan rammed Mar. ig eieii,

and the same being of a length greater-than the distance between saidshifter devices The shifter rods or devices 3 are provided on theiropposing faces with the stops on recesses 7 adapted preferably when thetransmission gears are in neutral position for lymg one at each end ofthe bore'5 between said shifter devices 3, the contour of said stopsbeing similar to the ends of the interlocking member 6. The stops or recesses 7 are of a suficient depth as to permit one end of theinterlocking member 6 tube r received within one of said stops duringsuch time as the shifter device at the opposite end of said interlock ismoved -from-neu-- 'tral position causing the wall surface thereof ateither side of said stop for contacting the end of said interlock. Itwill be apparent that the interlock precludes movement of one rod orshifter device from neutral position during such time as the other redis in operative or a position which causes 7 the movement of its stopfromregister with the bore 5.

The member 1 is formed with an upstanding portion 8 having a bore 9therein adapted at its lower end to intersect one of the bores 52, andwithin said bore 9 is mounted for reciprocating .movemen'tha locl'cingplunger 10, the lower end of which is forzzred with a locking tongue-11adapted on the downward movement of the bolt/for reception within thestop 7 of the shifter-rod or device 3 immediately below the same, saidtongue 11 being of a cross-sectional configuration corresponding to thestop or depression 7 and of an area adapted tofill said stop as in Fig.2of the drawings, whereby the interlockingmember 6 is forcedlongitudinally and into engagement with the stop 7" of the opposingshifter rod or device 3 marshy lo king ,the same from operative if maybe dispensed with, and the device may movement. In this constructionthev tongue 11 cooperating with one of the stops 7 looks one shifter rodor device from movement and forces the interlocking memberlongitudinally of the bore 5 to engage and lock the other shifter deviceor member from move ment, thus in this construction the member mountedwithin the bore 5 is capable of movement by the bolt to lock one of saidshifter rods or devices from movement, and when the bolt is retractedsaid member is moved by the operated shifter device or member tointerlock or preclude movement of the other shifter device or memberuntil such time as both members are returned to neutral position.

The locking bolt 10 is preferably of atype heretofore disclosed and usedin connection with other preferred embodiments of my inventions setforth in numerous patents heretoforegranted to me, and for the purposesof illustration the bolt is constructed with the flange 12 betweentheunderside of which and the lower end of the bore 9 is positioned -acoiled spring 13. surrounding the bolt, the tension of which normallyforces the bolt upwardly to withdraw the tongue 11 thereof from withinits cooperating stop 7. The bolt is also provided with a pawl receivingrecess 14' into which is adapted to be ro- -jected by the spring 15 thelocking paw 16 of an suitable type and adapted to be r'elease orwithdrawn by the operation of the eccentric end 17 of a key-operatedlocking barrel 18 of' any well known construction preferably of the typeset forth in copendmg application Serial No. 250,656 filed Au 20, 1918.The upper end of the locking b0 t 10 is adapted to project above theupper end of the bore 9 and said rojecting end affords a means forengaging the bolt to force the same downwardly into locked position asin Fig. 1 of the drawings. To prevent the bolt rotating the same isprovlded with a vertical guide or slot 19 into which projects the innerend of the-guide screw 20.

In my present device it will be apparent that I provide through thetongue'll and member 6, means whereby both rods orshifter devices 3 maybe locked from movement, and also provide when the tongue is withdrawn ameans whereby one of the rods or shifter devices is locked from movementduring such time as the other is moved from neutral position. By thepresent construction I dispense with one of the members necessary whenthe locking member or bolt is disposed centrally between the shifterrods or devices 3 and one looking member is positioned at each sidethereof for respectively engaging one of said rods or shifter devices. 7

It is apparent that by reducing the length of the member 6, theinterlocking feature position.

be solely, employed for locking the shifter devices. from movement, butit is to be understood that if the length of the member 6 is reduced,the thickness, widthor contour of the tongue 11 must be varied from thatillustrated in the disclosure, as said tongue must be necessarily of asuitable confirmation to force the opposite end of the member 6 intocooperationwith one of said stops when the tongue cooperates with itsassociated stop.-

Havin thus described my invention,

what I "c aim as new and desire to protect by Letters Patent is 'L-Thecombination with a plurality of longitudinally movable shifter devices,each rovided with a stop, a movable locking 1t adapted when in lockingposition to I engage with the stop of one of the shifter devices and adisengageable member ac tuated' by said position for engaging th stop ofthe .op-

bolt when moved into locking posing shifter evice whereby the saiddevices are held locked against longitudinal movement, and lockcontrolled means for locking the said bolt when moved to locking 2. Incombination with a pair ,of spaced independent] movable shifter devices,each provided wit a stop, a lock controlled lockmg bolt capable ofmovement for engaging one of said shifter devices to lock the same 'fromoperative movement, and a member interposed between said shifter devicesand moved by said bolt when in its latter osition into cooperation withthe stop, 0 the other shifter device to lock the same from movement.

3. In combination with a pair of spaced independently movable shifterdevices, each provided with a stop, a lock controlledlockmg bolt capableof movement for engaging one of said shifter devices to lock the samefrom-operative movement, and interlocking means interposed between saidshifter devices and ca able of coiiperation with the stop of one sh ofthe other shifter device to move its stop from coiiperation with the endof said interlocking member, said bolt adapted on its movement intocooperative relation with its associated stop to force said interlockingmeans into locked engagement with the other shifter device.

4. In combination with a pair of inde pendently movable shifter devices,each provided with a recess, an interlocking member freely movablebetween said shifter devices and the ends thereof adapted for receptionwithin said stops, said member being of-a--- ifter device on themovement said shifter devices for locking the same from movement and forfilling said sto whereby the opposite end of said interloc ing member isforced thereby into cooperation with the stop of the other shifterdevice to lock the same from movement.

5. In combination with a pair of arallel spaced independently movableshi r devices, each provided with a stop, a longitudinally movablelocking bolt capable of movement to cooperate with the stop of one ofsaid shifter devices to lock the device from movement, and a memberinterposed between said shifter devices and freely movable, said memberadapted for movement by said bolt when in its latter POSitififll-YEOcooperation with the stop of the other shifter device to lock the samefrom movement;

6. A means for simultaneously locking two spaced lpngitudinal membersfrom movement, the same comprising freely movable means positionedbetween said members and adapted for coiiperation at one end with one ofsaid members, and a plunger member capable of longitudinal movement intocooperation with one of said longitudinally movable members to lock thesame from movement and with 'said freely movable means, whereby one ofsaid lopgitudia nally movable members is locked from movement by saidplunger member "and the said freely movable means is forced into 00*operation with the other member by said plunger and locks the said otherlongitudi nal movable member from movement.

In testimony whereof I have signed my name to this specification in thepresence of a subscribing witness.
